LEF Magnesium Threonate is pricey (Jarrow's is less expensive) but as it has been involved in studies recently that prove it is the only magnesium that has the ability to cross the blood brain barrier I am trying it out. I have nearly finished one bottle and while I am not sure of its affect on my cognitive ability I do think the leg and foot cramps I was having have improved considerably.

Used to get the economical Source Naturals 180, but it's out of stock a lot for months at a time. This LE one is not that much dearer, but better for me because I like veg caps and doesn't go out of stock.

I have used this product for about a month, but have not seen an improvement in my memory. Maybe it is juts me. Other people might benefit from it because researches that I have read strongly suggest that L-Treonate improving memory.
